Momo Belia Deviluke

Momo Belia Deviluke has short, shoulder-length bob-cut pink hair accented by distinctive ahoge on both sides.

She straightens her naturally wavy hair to appear more mature, especially in later story arcs.

Her eyes are a striking shade of purple.

She stands 151 cm tall and weighs 45 kg.

Her three sizes are B78/W54/H78 initially, later growing to B80/W54/H79, with an estimated cup size increasing from C to D.

Despite being only 14 years old, Momo possesses a notably voluptuous figure, a source of both pride and teasing in the story.

She is often seen in refined or daring outfits, like oversized shirts, showing comfort with her appearance.

Momo is polite and graceful at first glance, always using formal language with most people.

Beneath this exterior, she’s resourceful, strategic, a bit devious, and has a sharp tongue—especially when provoked.

She’s known for her sadistic streak, especially when interacting with plants or in rare fits of anger.

Her younger twin, Nana Astar Deviluke, often accuses her of pretending to be sweet.

She’s proactive and self-disciplined, always striving to get what she wants.

Momo is emotionally mature in many ways, but when it comes to matters of love and intimacy, she shows a nervous, inexperienced, and surprisingly innocent side.

She deeply respects her older sister Lala Satalin Deviluke and wants to be recognized by her.

She is flirtatious but not reckless, wishing for genuine affection instead of casual play.

Her favorite saying is "a stroke of luck," revealing her opportunistic mindset.

Momo is the youngest of the Deviluke princesses, twin sister to Nana Astar Deviluke and younger sibling to Lala Satalin Deviluke.

She was born on August 8, blood type B, and is 14 years old—the same age as Golden Darkness.

She grew tired of palace life and rigorous studies, so she and Nana escaped from Deviluke and took refuge on Earth, moving into the Yuki household.

Her family includes her father Gid Lucione Deviluke and mother Sephie Michaela Deviluke.

She affectionately calls Lala “big sister.”

Upon transfer to Sainan High School, she quickly becomes a popular figure, even acquiring her own fan club, the Venus Momo Club (VMC).

Momo has the unique power to communicate with and understand plants across the universe.

She often acts as a translator for Celine, a plant who evolved into humanoid form.

Using Lala’s invention, the "Dedial," she can summon various plant allies to aid her in tricky situations.

Momo has notable engineering skills, having completed and activated a complex virtual RPG made by Lala.

She displays proficient hand-to-hand combat, and can unleash powerful beams from her tail, similar to her sisters.

She also is domestically talented, with Mikan Yuuki praising her for a natural flair in household chores.

Momo develops growing affection for Rito Yuki, drawn to his gentle behavior towards plants and people alike.

She becomes one of his boldest admirers, regularly sneaking into his room at night and attempting increasingly daring romantic advances.

Despite her confidence, she is shy about actual intimacy, vacillating between boldness and innocence.

Momo orchestrates the "Harem Plan" to ensure everyone can be happy—including herself, Rito, Lala, Mikan Yuuki, and even others—rather than just focusing on her own feelings.

She is deeply loyal to her sisters, especially Lala, vowing never to overshadow her and preferring to let Lala be Rito’s primary partner.

Despite frequent bickering with Nana, the sisters share a strong bond, always looking out for each other in times of real need.

She feels uneasy around Nemesis, whom she sees as a nemesis, and has difficulty handling those who can out-maneuver her, like Momioka Risa and Kurosaki Mea.

She is cordial and protective toward Mikan Yuuki, showing genuine concern in multiple incidents.

Introduction & Arrival

Momo first appears as a supporting character, arriving on Earth with Nana to investigate Rito Yuki’s suitability as a husband for Lala Satalin Deviluke.

They modify Lala’s unfinished game into the "Trouble Quest" to test Rito’s capabilities, roping in almost all the key characters.

Integration into Earth Life

After a brief return to Deviluke, Momo flees the palace to avoid studies, moving back to Earth and settling into the Yuki household.

There, she interacts daily with Rito, Mikan Yuuki, and other friends both at home and at Sainan High School.

Harem Plan

Witnessing Rito’s failed confession to Haruna Sairenji and understanding the mutual feelings between Rito, Haruna, and Lala, Momo launches her "Harem Plan."

She aspires to create a world where all of Rito’s admirers, herself included, can be happy.

To facilitate this, she transfers to Rito’s school, becoming a first-year in Class 1-B, making it easier to orchestrate encounters and build connections.

Her plan is built upon the condition that Lala retains her place as the main wife.

Romantic Struggles and Development

Momo’s bold attempts to seduce Rito are tempered by her own nervousness and inexperience.

She is devastated to learn of Rito’s deep feelings for Haruna.

Despite feeling defeated at times, Lala’s words encourage her, reigniting her resolve to continue working towards a shared happiness.

She becomes more reserved in her actions following her mother Sephie’s advice, but ultimately confesses her feelings to Rito and tells Sephie as well.

Momo’s favorite things include plants, tea, games, and surfing the galactic web.

She dislikes carrots and milk.

Upon transferring to Sainan High School, she quickly rises to idol status among boys, though she finds their advances annoying as her fan club grows more zealous.

She exhibits classic “loli voluptuous” traits—young looking, yet with a mature body.

She is talented in both plant communication and inventing, though her creations often result in unexpected, sometimes risqué trouble.

Though Lala and Run Elsie Jewelria are bold with Rito, Momo’s devotion is arguably the strongest.

She is even open to intimate contact with Rito in female form, highlighting her deep affection.

"I don’t mind what position I hold, Rito."

"Everyone here is someone important to me."

Momo’s design and personality are reminiscent of other lovestruck, cheeky heroines in the media.

She continues her "Harem Plan" even after the main plot concludes, hoping to create a happy ending for everyone.

Despite her cunning ways and devilish smiles, her ultimate wish is simple—loving and being loved in return, together with everyone she treasures.
